Application filed May 26, 1913. Serial No. 769,936.

To all "whom it may concern Be it known that I, FRANCIS X. MUDD, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inRailway-Cars, of which the following is a specification.

My invention relates to an improvement in freight-cars and, moreparticularly, in such cars as requiretobe ventilated through the roof toproperly equip them for the transportation, more especially, of livepoultry, which is the immediate purpose of my improvement.

Requirement of the United States Government makes it necessary toprovide, on the ordinary variety of freight-car, a running boardextending continuously, or unbrokenly', along the center of the car-roofand throughout the length of the car. This requirement has rendereduseless means hitherto commonly employed for ventilating these carsthrough their roofs; and it has necessitated the devising of aconstruction to comply with it whereby the indispensable and extensiveventilation through the car-roof shall'be attained.

The construction I have devised effectually accomplishes the ventilatingpurpose and conforms to the requirement referred to; and itis-illustrated in the accompanying drawings, in which- Figure 1 is aplan view of one-half of a freight-car roof embodying my improvement andshowing the hinged ventilating doors open on one side and closed on. theother; Fig. 2 1s a'broken view of the same in side elevation, with oneof the doors closed and'the other open; Fig. 3'is a sect-ion on line 3,Fig. 1; Fig. 4 is a section on line 4, Fig. 3, and Fig. 5 is a brokenplan view of the central part of the roof-structure.

The side-sections 6 and 7 of the freightcar roof are of ordinary or anysuitable construction and are supported at their inner edges on timbers9 upon posts 10 the lines of which flank a central longitudinal aisle ina live-poultry shipping car. The central space thus produced lengthwiseof the carroof is provided with an interstitial covering comprising bars11 spaced apart and supported at their ends on the timbers 9. Atintervals along this interstitial ventilating cover rise cross-beams 12,supported at their ends on the timbers 9 and having upwardly-convergingedges 13; and at each of these edges is rovided on the roof a cleat 14.The running-board 16 is supported on the cross-beams to extend inelevated position unbrokenly and centrally throughout the length of theroof. To the inner ends of the cleats 14 are hinged doors 17 forregulating the Ventilation and to close, in incleinent Weather, againstthe inclined edges of the 'cross-beams, with their free edges beneaththe overhanging edges of the running-board, and they are provided ontheir outer sides, at intervals, with transverse cleats 18 for proppingthe doors when they are laid back, in their opened condition,

- against the car-roof.

In a poultry-shipping car it is usual to provide a transverse centralaisle, or compartment, to accommodate the attendant and contain feed andwater-holding tanks; hence it is not customary to extend over thatcompartment the interstitial ventilating cover, which is therefore shownto be there omitted in the drawings.

What I claim as new and desire to secure by Letters Patent is- 1. In aventilated car-roof, a longitudinal opening in its center provided withan' 1nterstitial horizontal ventilating covering, cross-beams atintervals along said center and extending above the roo a runn1ngboardsupported in elevated position upon said beams to extend continuouslythroughout the length of the roofand form lateral openings beneath saidboard extending from the edges thereof to the roof, and doors extendingalong the ends of the series of said beams to be shut against them, forclosing said openings, and opened, for the purpose set forth. 7

2. In a ventilated car-roof, longitudinal openings in its centerextending from the car-ends short of its transverse center and providedwith interstitial horizontal ventilating coverings, a series ofcross-beams at intervals throughout the roof along said center andextending above the roof, an elevated running-board supported inelevated position upon said beams to extend continuously throughout thelength of the roof and form openings beneath said board extending fromthe edges thereof to the'roof, and doors extending along the ends ofsaid series of beams to be shutagainst them, for closing said openings,and opened, for the purpose set forth.

3. In a ventilated car-roof,- longitudinal openings in its centerextending from the car-ends short of its transverse center, a series ofcross-beams at intervals throughout the roof along said center,extending above the roof and havin upwardly-converging lateral edges, ane evated runningboard supported in elevated position upon said bars toextend continuously throughout the length of the roof and form openingsextending fromthe edges of said board to the roof and overhung by saidboard, and doors hinged upon the roof to extend along the ends of saidseries of beams and close against their said edges, for the purpose setforth.
